摘要
据2001-2003年粤北霜冻蔗区旱坡地3年3次新植、2次宿根试验结果,HoCP95-988特早熟高糖、高产稳产,萌芽性好、分蘖性强,有效茎多,宿根性强,对水肥条件要求不高,适宜霜冻蔗区及旱坡地种植。该品种11月上旬蔗糖分可达15.57%,分别比粤糖93-159和新台糖16号同期蔗糖分高1.68个百分点和2.24个百分点;榨季平均蔗糖分15.68%,分别比粤糖93-159和新台糖16号高1.14个百分点和1.71个百分点;平均蔗产量111585kg·hm-2,分别比粤糖93-159、新台糖16号增产10.0%和20.3%;平均含糖量17426kg·hm-2,分别比粤糖93-159、新台糖16号增产糖17.78%、34.31%。
According to the results from 2001-2003 variety trials on two upland and sandy soil sites in Yongyuan (frost region)sugarcane region, including two plant canes and three ratoon canes, HoCP95-988 is a new variety with very early maturity and high sucrose content, high and stable cane yields, good germination, strong tillering and ratooning ability, more millable stalks. It is suitable for sandy soils, upland and frost regions. The mean cane yield and sugar yield in cane of HoCP95-988 were 111 585 kg·hm^(-2) and 17 426 kg·hm^(-2), respectively, which were 10.0% and 17.78% higher than those of YT93-159(main check variety), respectively, 20.3% and 34.31% higher than ROC16 (vice check variety), respectively. The sucrose content in cane of HoCP95-988 in early November and mean value (from early November to early January in next year) were 15.57% and 15.68%, respectively, which were 1.68% and 1.14% (absolute value) higher than those of YT93-159,respectively,2.24% and 1.71% (absolute value) higher than those of ROC16, respectively.
